Quite a few people have tooled around with playing music on stepper motors, which are an integral component in a 3D (or, indeed, any) printer. Dahlstrand figured that if he could get a stepper motor to play music, couldn't he get it to print at the same time?

At the 2013 Art Hack Day in Sweden, he demonstrated his Frankenstein's printer at work. "The stepper motors controlling the movement can be run at different speeds, the speed decides the pitch of the sound and makes it possible for the motors to make music," he explained. "Three motors each represent one of the tracks, and their movement makes a unique pattern.

"The two motors controlling the Z-axis moves only slightly to increase the height. Microphones on the motors picks up the sound and amplifies it."
